Asian carp barriers proposed

A new report from the
Great Lakes Commission outlines several options to
separate Chicago area waterways from the Great Lakes to help prevent the spread of the dreaded
Asian carp.

These voracious fish, which out-compete native fish for food, are considered a dire threat to
Lake Erie's tourism and sport-fishing industries. The report,
which is
available here, outlines
several
methods (actually, three options) to separate Chicago's waterways from Lake Michigan.

Several DNA tests have indicated fish have alread passed an electronic barrier erected by the
Army Corps.

The proposals, however, would cost at least $3 billion and take several years to complete.
